JOHN NATHAN, or CoUToLENc, CALIFORNIA ELECTRIC HEATER.

To all whom t may concern.

Be it known that I, lJOHN NATHAN, a sub-f jectof the King of Great Britain, residing at Coutolenc,'in the county of Butte and State of California, have invented new'and useful Improvements in Electric Heaters, of` which the following is a specification.

An object of the invention is to provide an electric heater for use in heating fluids and the like.l

The invention embodies, among other fea tures, a device that is particularly adapted for use in receptacles containing fluids and in which it is desired to heat the fluid, such as steam tables, pereolators and other heating receptacles.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the vieivs, and in which:

Figure 1 is a horizontal sectional view of my device; Fig. 2 is a vertical transverse sectional view taken on the line 2--2 in Fig. 1: Fig. 3 is a perspective view of the insulating holder: and Fig. 4 is a perspective view of the insulating collar.

Referring more particularly to the views, I disclose a fragmentary portion of a steam table 10, adapted to contain a fluid such as water'andA which it is desired to heat by electricity. A shell 11 is provided with an integral tubular portion 12 through which suitable electric Wires 13 are passed, the s idwires being inclosed in a tubular end 14 of a holder 15, arranged Within the shell 11, the mentioned holder being preferably made ofinsulating material such as hard rubber With the wires 13 passing therethrough as shown, the tubular end 14 of the holder 15 being arranged within the tubular portion 12 of the shell 11 and the said holder having a series of openings 16 there# in in which are mounted the ends of elcctrodes 17, having the ends of the` wires 1? connected thereto to supply the electrodes 17 with electric current and heat the same.

In order-to secure the electrodes 1T rigidly Specification of Letters Patent. i Patented June 424 1913 Application filed OctoberI 2, 1912. Serial No. 723,543.

eral edge thereof, being cut away to form aV circular seat 21 adapted to be engaged by a member L3, said head 22 having threaded connection with the shell 11, the peripheral ,surface of the securing member 23`being provided with threads 24 having connection with the steam table'10 as shown.

Although 'I have described'my device asY used in qonnection with a steam table, it will be understood that the same can bevemployed in connection with various other receptacles or articles constructed for the purpose of heating fluid.

' `Having thus described vmy invention, 1 claim:

-1. In a device 'of-the class described, the

tubular portion, of an insulated' holder wit-hin the shell and having a tubular yend encircled by the tubular portion of the holder. electrodes mountedl in openings formed in the said holder and arranged in spaced relationY thereon, a collar encircling the said electrodes, flanges on the said collar and projecting into notches in the electrodes` a seat formed on the collar, and a securing member adapted for engagement with the seat of the said collar and having threaded connection with the said shell.

2. In a device of the class described, the `combination with a shell. of a' holder therein. electrodes mounted on the said holder, wires extending through an opening in the shell and the said' holder and having connection with theI said electrodes, a collar enextending into notches in the electrodesto l secure the electrodes in position on the l holder. and a securing member engagingthe l collar and having threaded connection with the said shell.

In testimony whereofl affix my signature in pre'sence of two witnesses.
